Nowadays, using cryptographic systems play an effective role in security and safety technologies. One of the most applied kind of cryptography is Symmetric Cryptography and its applications. New aspects of symmetric Cryptography methodologies and applications has been presented by this paper. Security-based networks and some complex technologies such as RFID and parallel security settings has been introduced by using Symmetric Cryptography is the main base of discussion in this paper. Designing a unique protocol for Symmetric Cryptography in security networks elements is the focus.
